There is known an electrolytic cell for performing electrolysis of water. In the electrolysis of water in an electrolytic cell using a solid polymer electrolyte, a catalyst electrode is bonded to both surfaces of a cation exchange membrane, and a current collector such as a conductive metal is brought into close contact with the bonded electrode and energized.

く、物質の大量生産を目的とした大型の電解槽を得るこ
とは困難であった。In an electrolytic cell using a solid polymer electrolyte, since the distance between the anode and the electrode is small and there are no bubbles between the solid polymer electrolyte and the electrode, it is necessary to apply a low voltage and a large current density. And the conductivity of the electrolyte is not used, so high-purity water with extremely low conductivity can be used as the raw material water, and high-purity hydrogen and oxygen can be obtained. It has the feature of. However, when joining electrodes to solid polymer electrolytes,
It is difficult to form a large-sized electrode with stable quality, and it is difficult to obtain a large-sized electrolytic cell for mass production of substances.

圧の上昇等が生じるので好ましくない。Therefore, in order to obtain an electrolytic cell using a large-area solid polymer electrolyte, the anode and the cathode were not directly joined to the solid polymer electrolyte, but an electrode made separately from the solid polymer electrolyte was used. There has been proposed an electrolytic cell in which both surfaces of a polymer electrolyte are adhered to each other. For example, FIG. 4 shows an electrolytic cell in which electrodes are stacked on and adhered to both surfaces of a solid polymer electrolyte. FIG.
(A) is a front view of the solid polymer electrolytic cell, and FIG.
FIG. 4B is a cross-sectional view taken along line AA in FIG. A large number of solid polymer electrolytes 31, anodes 32, cathodes 33, and bipolar plates 34 are laminated, and end plates 35 and 36 are fastened with many fastening bolts 37. However, in such an electrolytic cell, when the electrode area is large, it is inevitable that the end plate surface is distorted, and when the number of laminations is large, an electrode with non-uniform contact is generated. Of the contact between the anode and the anode 32 and the cathode 33, unevenness of the current flowing during the electrolysis occurs, and deterioration of the solid polymer electrolyte and the electrode due to the occurrence of a portion where the current is concentrated, or the electrolytic voltage Undesirably increases.
